摘要： An outboard motor steering system for an outboard motor mounted on a stern of a boat and having an internal combustion engine at its upper portion and a propeller with a rudder at its lower portion that is powered by the engine to propel and steer the boat, having a swivel shaft connected to the propeller to turn the propeller relative to the boat and housed in a swivel case, a hydraulic actuator such as a double-acting cylinder connected to the swivel shaft to rotate the swivel shaft, a hydraulic pressure supplier connected to the hydraulic actuator to supply hydraulic pressure, and a controller that controls supply of the hydraulic pressure to the hydraulic actuator in response to a steering signal inputted by an operator such that the outboard motor is steered relative to the boat. In the system, the hydraulic actuator and the hydraulic pressure supplier are housed in the swivel case. The system is thus simply configured to avoid increase in number of components and weight, and does not cause a problem regarding space utilization and operation efficiency, while improving steering feel.

摘要： In an outboard motor steering system for an outboard motor mounted on a stern of a boat and having an internal combustion engine at its upper portion and a propeller with a rudder at its lower portion powered by the engine to propel and steer the boat, a controller is connected to an actuator to rotate the outboard motor relative to the boat, and controls the actuator in such a manner that steered angle of the outboard motor relative to a steering angle inputted through a steering wheel becomes a predetermined ratio that is changed such that the steered angle of the outboard motor relative to the steering angle decreases with increasing moving speed of the boat. Alternatively, a switch is provided to be manipulated by the operator and generating a signal indicative of an instruction to change the steered angle of the outboard motor when manipulated; and the controller controlling the actuator to steer the outboard motor to an angle in response to inputted steering angle when the switch is not manipulated, while controlling the actuator to change the steered angle when the switch is manipulated. With this, the burdens of the operator are lightened and the steering feel is improved, in particular when the operator steers the boat to approach or leave a quay.

摘要： An outboard motor steering system wherein an electric motor is installed inside the outboard motor and the output of the electric motor rotates a swivel shaft to steer the propeller, thereby enhancing steering feel by using an electric motor to enable highly responsive and accurate control. In addition, the configuration is simple and does not lead to an increase in number of components or weight. In another steering system wherein a first hydraulic cylinder for driving a steering system and second hydraulic cylinders for driving a power tilt-trim system are supplied hydraulic oil from the same pump, thereby making a dedicated hydraulic pump for the steering system unnecessary and thus enabling reduction of system size and weight. In still another steering system wherein the outboard motor main unit is swiveled to turn the propeller by extension/contraction of the hydraulic cylinder whose one end is attached to the outboard motor main unit and other end is attached to the boat side of the outboard motor. In a plan view taken in the gravitational direction, moreover, the hydraulic cylinder is located inside the vertical projection plane of the profile of the outboard motor main unit, so that the hydraulic cylinder never projects outside the outboard motor main unit no matter how much it extends or contracts.

摘要： An outboard motor steering system for an outboard motor mounted on a stern of a boat and having an internal combustion engine and a propeller with a rudder powered by the engine to propel and steer the boat. The system includes a swivel shaft connected to the propeller, a swivel case rotatably accommodating the swivel shaft, and a hydraulic cylinder connected to the swivel shaft to rotate it. The swivel case is formed with a box-like recess to accommodate the hydraulic cylinder therein such that the hydraulic cylinder does not project outside a profile of the outboard motor, regardless of a steered angle of the outboard motor. A rotation angle sensor is also installed in the recess and outputs a signal indicative of an angle of swivel shaft rotation. Further, moving orifices are provided in a hydraulic pressure circuit of the actuator for relieving excessive hydraulic pressure. Thus, space utilization around the outboard motor and boat is not restricted and steering feel is improved.

摘要： An outboard motor steering system for an outboard motor mounted on a stern of a boat and having an internal combustion engine at its upper portion and a propeller with a rudder at its lower portion powered by the engine to propel and steer the boat. The system includes a swivel shaft connected to the propeller to turn it relative to the boat, a swivel case fixed to the outboard motor and rotatably accommodating the swivel shaft, and a hydraulic actuator connected to the swivel shaft to rotate it. The actuator has a shape whose height is larger than its width and is installed in such a manner that a direction of the height is in parallel with a vertical direction, so as not to project outside a profile of the outboard motor, obtained by looking down the outboard motor from downward, regardless of a steered angle of the outboard motor. Specifically, the actuator is two hydraulic cylinders installed in an over-under manner or an elliptic hydraulic cylinder having a plurality of piston rods installed in the same manner. With this, it can enhance the output of the actuator to increase the steering force (torque), can prevent the actuator from projecting outside the profile, and can avoid constriction of the space around the outboard motor.
